Be it known that I, BENZION KARFroL, a citizen of the United ates of America, and a resident of the borough of Brooklyn, county of Kings, city and State of New York, have invented certain new and useful Improve ments in Apparatus for Perforatin ing Pa er or other Sheet Materia of which the fol owing is a s ecification.

My invention Felhtes to a novel means for perforating paper or other sheet material,

aving perhaps particular reference to what is known as lace-paper, or paper which is perforated for ornamental purposes.

In my apparatus instead of perforating the paper or other material b forcing a cutting-tool directly through the sheets, and thus at once effectin the perforation or division, I have provided means for first indenting the sheet material so as to produceon one side thereof certain elevations or protuberances along the lines on which it is finally to be divided or perforated, and, further, means for then treating this indented but unfinished product in such a way as to cause the elevations thereon to be removed; whereby the material is divided and holes or perforations are made to appear therein along the desired lines.

The advantages of my invention are various. In the first place I need no high pressure at the dies, as would be the case were the cutting done directly through the sheet. Again, I avoid the necessity of troublesome and special provision for t e removal from the machinery of the pa er or other cuttings the re is 5, 6, and 7 have been maintained or particles due to the division of the mateagainst each other under great pressure and ria As is Well known, where in the manu-; the s act has been perforated between rolls 6 and 7 b T thereon. pressure between r0 6 and 7 is only shflicient to indent the paper. From roll 7 the pa er passes up to an ab'rading or. cutting rol er 8, being held r" siliently against the face thereof by any s it- .able pressuredevice, such as a bent spri' g piece 9, mounted on sup orts 10 and 11, havmg adjustments 10 an 11' for varying the pressure of the paper on the roll.

It will benoted that the abradi lOllGl. 8 is on the same. side'of the paper as t a roll 7, whereby the prttulierances or in entatious 12, (see Fig. 4,) projected on that side of the paper by' the r0 1 6, may coma into contact facture .of lace-paper" perforating-dies are used high pressure must be maintained at the dies, and there results, even when the machinany is operating most efficiently, injury to the fabric of the paper, often a tear mg of it, and also injury to the machinery. Moreover, there presently results yet more serious injury by the clogging of the dies by c oggings. at once 11npalr the efiiciencyof the cutting apparatus and bytheir resence in the dies in ure the aper. Furt ermore by accumulation and y being forded into the dies at high pressure I orcldgged particles soon injure and render worthless the dies.

Having briefly set 'forth the nature and 6 is a steel roll having,

the coacting edges of the dies n my ap aratus, however the with the roller 8. The roller 8 has a surface of emery, ground glass, or other suitable abrading material and'is driven in any suitable manner. This revolving surface removes the elevations from the surface of the paper, and naturally the desired perforations 13 (see Fig. appear in their places. From the roll 3 the finished paper passes to a takeup roll 14.

in the drawings I have shown a second strip of paper 15, being fed from a second supply-roll 16 to the idler 3, where it is superimposed upon the strip 1 and thus positioned passes through the steps described in connection with the latter. This second stri of paper may or ma not be employed. referably, however, use two strips, for the one. tends to support the other, and thus make the indentations produced at the rolls 6 and 7 finished article.

more rigid or stable, whereby they may stand up better to the cutter 8.

In the application of my invention to the manufacture of lace-paper the roll 7 would ordinarily be the usual embossing-roll. In passing between the rolls 6 and 7 the paper would therefore receivethe usual emboss ings on its upper or face side, while the indentations made by the roll 6 would appear on the reverse or under side.

My invention is thus seen to comprise two distinct and im ortant features. In the first operation 0 my apparatus it will be noted that I produce an unfinished articlenamely, a paper or other sheet material on one side indented but as et uncut. This article is novel with me an is characteristic of my invention. The second operation of the apparatus consists in a treatment of the indented paper to cut or divide from the body its indentations or elevations produced in the first operation.

Since in my invention the cutting is done by removing the elevations on the surface of indented sheet material, the necessity for means for punching through the sheets is obviated, and consequently my invention in its broadest application admits of a selection of ruttingmeans or methods, thus making possible more efficient cutting and a better For instance, a knife-edge by its nature is likely to injure a fabric, such as paper, and yet heretofore it has been the most practicable means for cutting. Inmy invention, however, as I simply have protu-. berances or indentations to remove I prefer to grind off the same. Grinding involves no dies to become clogged and makes it aneasy matter to take care of the paper )articles removed from the sheet. The per orations or divisions may by grinding be made practically perfect, in that the elevations or protubcrsnces may be removed flush with the surface of the sheet without any chance of in jury to the latter, A grinding-tool, even if in con act with the face of the paper, will not roviding the encatch or injure the same;

the paper is to gagement of the tool wit some extent yielding.

In the removal of grinder I rely on the natural stability of the pa er fabric to enable the elevations or protu erances to stand up against the action of the grinding-tool. The fabric being more or less delicate, however, it should not be held in absolutely unyielding engagement with the tool. Unless free to have some sli ht movement relative to the face of the in er the material would be cut by the latter and torn. Therefore where the material passing in a sheet over the grinder from the mdenting to the take-up rolls would not by virtue of its character and the length of the sheet have sufficient resiliency of movement at the grinder a further means for providing resilient engagement of the sheet and rinder is introduced. In the present case? have shown the paper as bearin lightly on the grinding-r01 by reason of t e action of the sprin 9. Other means for obtaining a resilien engagement of the grinder with the indented material may of course be substituted for that shown.

Where in some instances the fabric may be particularly delicate or flimsy, I superimpose a plurality of sheets of the same before the indenting step. The sheets then indented, the pyramids or indents thereon be in presented to the grinder in multiplex, .wil stand up to the latter, so as to be cut cleanly and effectively, no matter how delicate the texture may be Additional advantages of my invention are then that a number of sheets may be pre ared simultaneously and that regardless o the nature of the fabric the paper can be divided without injury thereto.

Whereas I have stated my invention as articularly adaptable to the manufacture of ace-pa er, it is obvious that it may be equally adapta le and useful in almost any instance where paper is to be divided or perforated. My invention may, for instance, be employed to great advantage in the manufacture of dress-patterns In such use it is merely necessary to indent the pattern-paper along the line of the pattern to be cut, leaving an occasional break in the indent in order to provide means for maintainin the attern in the sheet until it is desirab e to etach the same. Then upon division of the patternpaperalong the line of the indentation the pattern will be severed, except for the retaining-pieces left at the points where the indent was broken. The pattern may thus be made in a simple and expeditious manner by merely assing the paper through the steps of my lnvention heretofore described, and the pattern-sheets emerging from the machine are at once ready for shipment and use.

Obviously my invention is not confined to the elevations by the i the division or perforation of paper alone. The invention is applicable wherever any sheet material of a nature to be indented in the manner described is to he cut or divided for any purpose. For instance, by my process the ornamental trimmings of brass or other metal used on picture-frames, furniture, and elsewhere are readily and effectively made. The variety of the material and the; purposes for which. such may be used when out in accordance with my invention are innumerable.
